MACHINE FOR CONSTRUCTING BOXES.

SPECIFICATION forming part of Letters Patent No. 366,538, dated July 12,1887.

(No model.)

To all whom, it may concern:

Be it known that we, J. ERWIN \VAKEMAN and ROBERT L. Gnooxna, citizensof the Uni ted States, residing at Lockport, in the county of Niagaraand State of New York, have invented a new and useful Machine for MakingBoxes.

This invention pertains to certain new and useful improvements inmachines foreonstructing boxes; and it consists in the detailedconstruction, combination, and arrangement of the parts, substantiallyas hcrei nafter des ribed and claimed.

In the accompanying drawings, Figure 1 is a plan view of our invention.Fig. 2 is a longitudinal sectional view tl1ereof,and Figs. 8 and 4 aredetails.

In carrying out our invention we secure to a board or table, A,an'approximatel y Vshaped plate or iron, B, which has apertured projecting lugs I), whereby the same is secured by means of screws to the uppersurface of said board or table, as shown in Fig. 1.

C is a plate disposed a short distance from the V-shapcd plate or ironB, the-vertical portion of said plate 0 being disposed against theopposite side walls of an aperture or opening, G, formed in the board ortable A, and the horizontal projecting portions or lugs of said plateare apertured for the insertion of screws for retaining the sameinposition. This plate has oppositely-disposed apcrtured lugs I) 1),between which is pivoted a cam-lever, D, the cam-like end of which beingfaced toward the V-shaped plate or iron l3, the purpose of which willsoon appear.

Dis a movable block having right-augularly disposed arms (Z (Z, thevertex of which is,when the block is in position, directly opposite thevertex of the plate B, as shown. This block has grooves in either sidethereof for sliding on horizontally-projecting ways (1 d of the plate 0,and within a central longitudinal aperture of this block is disposed ashouldered pin, (1, a spring, (1 also disposed therein, bearing againstthe shoulder on said pin. The outer end of this spring-pressed pin dbears against the forward wall of the aperture formed in the board ortable A, and the normal action of the spring on the pin is to cause therear vertical end of the block D to bear directly against the cam-likeend of the lever D, the purpose of which will now appear.

This invention, it will be understood, is in tended for putting togetherboxes having sides composed of single pieces of wood, the ends of 5which pieces are dovetailed for fitting in correspondiugly-shapedinortises or sockets in the adjoining right-angularly disposed side ofthe box. This being the intention, the same is can ried into effect byplacing opposite corners of the box undergoing construction in theopposite vertexes of the plate or iron 13 and sliding block D, and byforcing down the lever D the cam-like end thereof will'causc the slidingforward of the said block as against the action of the spring iuclosedtherei n,and thus effectively secure thcjoiuted ends of the box.

Having thus described our invention, what we claim, and desire to secureby Letters latent, is

1. The hereindescribed machine for construeting boxes,consisting oftheboard or table, the V-shaped plate or iron, the plate having projectingways, the sliding block having the spring and shouldered pin iuclosedtherein,

and the cam-lever arranged substantially as shown and described.

2. The combination, with the board or table and the V-shaped plate oriron secured thereto,

of the sliding block having a central aperture J. ERW'IN XVAKEMAN.ROBERT L. OROGKER.
